His nickname is “Money,” so it was no surprise this past week when Floyd Mayweather Jr. signed a six-fight, 30-month deal with a premium cable network.

What wasn't expected was his decision to go with Showtime/CBS and not rival HBO, his longtime television home.

Details have not been disclosed, but some are reporting the deal topped the $200 million mark.

“I got a divorce,” he said of leaving HBO. “I'm married again.”

At the same time, Mayweather also announced his opponent for his return to the ring May 4 — a year since his last fight. The sport's pound-for-pound king will defend his WBC welterweight crown against interim titlist Robert Guerrero at the MGM Grand in Las Vegas.

While perhaps not a pushover, at least on paper, Guerrero certainly is not a high-profile opponent.

So the focus will be on the Showtime deal and not the fight.

All part of the Mayweather plan, a diversionary tactic?

Probably so.

Mayweather, who turned 36 today, is a master at making a splash while figuring out a way to avoid getting wet. He seeks to take the least risk for the most reward.

But make no mistake, his jump to Showtime is significant. How much so remains to be seen.

It was a move many say will alter the landscape of boxing.

HBO long has been viewed as the big brother when it comes to the sport, dominating its rivalry with Showtime for decades.

Showtime apparently simply outbid HBO for Mayweather's services. “Money” also likely was won over by the promotional reach of CBS, which owns Showtime.

HBO's parent company, Time Warner, doesn't own a free network and can't match the exposure CBS can offer.

Mayweather's fight with Guerrero will receive heavy promotion on various CBS outlets, including during the NCAA basketball tournament and Final Four.

In the end, the deal with Showtime simply came down to the bottom line.

“HBO made a great offer, but the Showtime offer was substantially greater in every facet,” Leonard Ellerbe, one of Mayweather's top advisers, told espn.com.

In other words, HBO simply got outgunned.

But not everyone is convinced Showtime has become top dog in the boxing business.
